Overview

Windows 8.1, now with a new Start screen

With the new Windows, you can watch movies or play games with Xbox, Skype with friends, get work done with Office, access files anywhere with OneDrive, or find your next favorite app in the Windows Store. And you can get to it all from the new Start screen, even your familiar desktop.

Your familiar desktop

From the Start screen, you're just a click away from the familiar Windows desktop you know, so you can do the stuff you’ve always done.

Your own unique start screen

Personalize your Start screen with your favorite news, friends, social networks, and apps. Customizable colors and backgrounds and four different sizes of tiles make your Windows as unique as you are.

Works hard, plays hard

Windows 8.1 gives you the power to quickly browse, watch movies, play games, polish your resume, and pull together a killer presentation — all on a single PC. Now you can organize up to three apps on your screen at once in a single view.

The apps you want

In addition to great built-in apps for email, people, photos and video editing – you can also download thousands of popular apps from the Windows Store, including Netflix, ESPN, Skype and Halo: Spartan Assault.

Mouse, keyboard, and now touch

Windows 8.1 works with different types of devices, including touch, mouse-and-keyboard, or both. Discover fast and fluid ways to switch between apps, move things around, and go smoothly from one place to another.

Your Office, your way

Experience Office at its best on Windows 8 devices. Discover new and better ways to create, edit, and browse—using a keyboard, pen, or touchscreen. Microsoft Office sold separately.
